peroxide‚ is toxic to the cell in high amounts. Catalase is a very efficient enzyme‚ it has one of the highest rates of reaction among all of the enzymes. Enzymes have high specificity‚ generally enzymes catalyse only a single chemical reaction or a set of closely related chemical reactions. Enzymes do not affect the products of the reactions they catalyze‚ they only hastens the reaction process. Figure 1. Diagram showing the energy required on catalyzed and uncatalyzed reactions Enzymes technically

The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

But I think it happened because the blow dryer only focuses on one point so it doesn’t effect the other vanes. When I used the power of wind‚ I realized that the result was so much

Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules)‚ all of which are in constant‚ random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases‚ such as pressure‚ temperature‚ or volume‚ by considering their molecular composition and motion. Essentially‚ the theory posits that pressure is due not to static repulsion between molecules‚ as

Application of linear algebraic equation for chemical engineering problem The chemical engineering system models often outcome of set of linear algebraic equations. These problems may range in complexity from a set of two simultaneous linear algebraic equations to a set involving 1000 or even 10‚000 equations. The solution of a set two or three linear algebraic equations can be obtained easily by the algebraic elimination of variables or by the application of cramer’s rule. However for systems involving
